6.2.20 F23: PWM Control Parameter
Ref. code Function Description Setting Range [Default]
F23.00
Carrier frequency
1 - 8 [6kHz]
F23.00 defines the carrier frequency of PWM output wave.
• The carrier frequency will affect the running noise of the motor. The higher the carrier frequency, the
lower the noise made by the motor. So properly set the carrier frequency.
• When the value > factory setting, DH3N should be derated by 5% when per 1kHz is increased compared
to the factory setting.
F23.01
Auto adjust carrier frequency
0 - 2 [1]
0: Prohibited.
1: Adjust 1.
2: Adjust 2.
• HD3N auto asjust the carrier frequency according to output frequency and heatsink temperature.
• Auto adjust is invalid under torque control.
F23.02
PWM overshoot enable
0,1 [1]
0: Disabled.
1: Enabled.
F23.03
PWM modulation mode
0,1 [0]
0: Switch between two phase/three phase.
1: Three phase.
F23.04
Switch point 1 of PWM modulation mode
5.00 - 50.00 [5.00Hz]
F23.05
Switch point 2 of PWM modulation mode
7.00 - 50.00Hz [10.00Hz]
PWM modulation mode applies to V/f control and carrier frequency > 3kHz; HD3N selects three phase
modulation for open loop vector control or carrier frequency ≤ 3kHz.
Note: upper limit of F23.04 = F23.05 - 2.00Hz, lower limit of F23.05 = F23.04 + 2.00Hz.
F23.09 Random carrier factor K1 0 - 2000 [2]
F23.10
Random carrier factor K2
0 - 2000 [3]
